Problem iPod Touch Redsn0w

Hi,
i have a big problem... Since 2 days i've got jailbreak.
Today at the morning i want to use my ipod, but i was not able to go to the locksreen, using the power-button...
every time i want to lock, it dosn't work... but i was able to reboot...
now i'm at home and i want to boot my ipod via redsnow iboot cms...
but i'm not able to start dfu mode... i need to restore my ipod... because, its not possible to send my ipod to the store there i have bought it. because of jailbreak...

So, you've tired the patch to boot it, right? I'm a little confused as to what your problem is, but, when your trying to put it into DFU mode make sure to really have the time correct, because if you don't hold it long enough it won't work. If that doesn't work you can just try the restore button in itunes and it'll put it back to default settings.

how should i get it in dfu?
i connect the ipod with my pc. xp told my that it don't recognizes my pod
i press and hold power+home fpr 10 sek, after that i hold only home for 5 sek...
yesterday it was working fine... but not at this moment
